Radiology

Chapter 2 Vocab

TermDefinition
Absorbed Dose Amount of energy deposited in any form of matter, by any type of radiation.
Background Radiation Ionizing radiation always present in the environment.
Characteristic Radiation Produced when an electron from the tube filament connects with an orbiting electron.
Coherent Scattering Low energy x-ray passes near an atoms outer electron, which results in a scatter but no loss of energy.
Compton Effect Dental x-ray interacts with an orbital electron, and the x-ray energy is transferred to the electron.
Decay Happens when an unstable isotope tries to regain stability by releasing energy.
Dose When the radiation is absorbed into the tissues.
Dose Equivalent Used for radiation protection to compare the biological effects to various radiation. Absorbed dose x biological effect.
Effective Dose Equivalent Used to compare the risk of the radiation exposure producing a biological response.
Electromagnetic Radiation Movement of wavelike energy through space as a combination of electric and magnetic fields.
Exposure The measurement of ionization in air produced by x-rays.
Frequency Measurement of waves that pass a given point per unit of time.
Gray (Gy). Unit for measuring absorbed dose.
Hard Radiation Radiation with great penetrating power.
Ionization Is the formation of ion pairs.
Ionizing Radiation Radiation that produces ions.
Photon Bundles of energy that travel at the speed of light.
Rad Radiation Absorbed Dose
Radiation Emission and movement of energy through space.
Radiolucent X-rays appear dark gray or black.
Radiopaque X-rays appear white or light gray.
Rem Unit for measuring dose equivalent.
Roentgen (R). Unit for measuring exposure.
Secondary Radiation Travels the opposite direction of original x-ray.
Sievert (Sv). SI unit for measuring dose equivalent.
Soft Radiation Limited penetrating power and unsuitable for exposing dental radiographs.
Wavelength The distance between two crests on a wave.
